pi(3.14) divided circumference

Take "pi" times the diameter of the circle. Pi = 3.14159 (ALWAYS) If circle has a diameter of 10cm, circumference 31.41cm If circle has a radius of 2inches, the circumference is 12.57 inches. (radius = 2, diameter = 4)

The circumference = pi x r2, and the diameter = 2r. So if you start with the circumference, you divide that number by pi (3.1416), then take the square root. What's left is the value of the circle's radius; double it to get the diameter.

Diameter = Circumference/pi

Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter

Divide the circumference by pi, and that will give you the diameter.

Multiply the diameter by pi (approximately 3.1416) to find the circumference.

pi(3.14) divided circumference

You multiply the diameter by Pi (about 3.1416). The result is the circumference:8m x 3.1416 = 25.1328 meters circumference

Circumference equals pi times the diameter, so you would divide by pi. (3.14159265...)

Well the formula for that problem is C=Pi*d or circumference= 3.14 times the diameter. Figure it out from there.

Use the following formula to figure diameter when the circumference of a circle is known: Circumference = Pi x Diameter 20 = 3.1415927 x D D = 6.366

Circumference = 2*pi*radius or diameter*pi

The formula for the circumference (C) of a circle is C = 2πr or C = πD, where r is the radius and D is the diameter. If you know the circumference then C/π = D So just divide the circumference by pi to get the diameter.

The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.

There is no such thing as "the diameter of the circumference" of a circle. A circle has a diameter, and a circle has a circumference. If you know one, you can always figure out the other one, because they're very tightly connected. Circumference = (diameter) times (pi) Diameter = (circumference) divided by (pi) "pi" = about 3.1415926536 (rounded). You can use 3.14 and your answers will be very close.

Circumference = 2 x {pi} x radius = {pi} x diameter
